nginx 整合 ngx_http_accesskey_module 模块的应用
原发于http://www.linux-ch.com/post-25.html
现有一文件分享系统,利用nginx平台直接打开目录功能,可自由浏览并选择文件进行下载.同时开通ftp,可以上传文件与大家分享.这一切实现起 来并不困难,但在一段时间后发现分享系统的流量较高,后通过分析日志发现竟然是来自各地迅雷的链接.在这之后我曾将迅雷的agent给过滤掉,效果还不 错,但随之而来的问题是:平时我们也在使用迅雷,对于小文件没什么影响,但对于动不动就上G的文件,对于浏览器的下载功能是个严酷的考验. 现在利用ngx_http_accesskey_module模块,并配合php,一个能防止下载工具我链接分享功能的文件分享系统复活了~
nginx的编译配置请参考http://wiki.nginx.org/NginxHttpAccessKeyModule
下面分享下关于我的配置:
nginx:
location /downloads {
# autoindex on;
# autoindex_localtime on;
# autoindex_exact_size off;
accesskey on;
accesskey_hashmethod md5;
accesskey_arg "key";
accesskey_signature "mypass$remote_addr";
}
# autoindex on;
# autoindex_localtime on;
# autoindex_exact_size off;
accesskey on;
accesskey_hashmethod md5;
accesskey_arg "key";
accesskey_signature "mypass$remote_addr";
}
php源码:
<?php
$downfile=$_GET["downfile"];
$dir0='/web/html/downloads';
$dir1=str_replace('..','',$_GET['dir1']);
$dir=$dir0.$dir1;
if ($downfile) {
$filename =basename($downfile);
$file=fopen($dir."/".$filename,"rb");
Header("Content-type: application/octet-stream");
Header("Accept-Ranges: bytes");
Header("Accept-Length: ".filesize($dir."/".$filenamee));
Header("Content-Disposition: attachment; filename=".$filename);
echo fread($file,filesize($dir."/".$filename));
fclose($file);
exit;
}

源码原来是使用urlencode这个参数对链接进行转换的,遇到空格就出问题,后改用rawurlencode将问题解决.
php的源码是在网上找回来修改加工的,在此我要感谢3t,有他的帮助我才能改好这些文件,当然也要感谢将源码发布出来前辈,这样我才有机会去修改这些,谢谢.
